Regarding N#1493, there is an inconsistency with the 2016 business strike mintages. Namely, 2016 (W) and 2016 (P) are given their own mintage entry while 2016 (S) is not and shares its entry with “2016”.
PCGS provides a separate catalogue entry for 2016 (S).
- 2016 $1 Silver Eagle 30th Anniversary (#570522)
- 2016-(P) $1 Silver Eagle (#624786)
- 2016-(S) $1 Silver Eagle 30th Anniversary (#593534)
- 2016-(W) $1 Silver Eagle 30th Anniversary (#570523)

These four mintages are visually identical with no mint marks present. That's an argument to collapse these entries to a single “2016” entry. However, other year mintages seem to distinguish coins without mint marks that can be traced to a specific mint. I feel that 2016 should be consistent with other years (and PCGS and NGC) and adopt a distinct entry for “2016 (S)”.
